I think that the more you kill other players the more you go insane so you start to see hallucination such as dead bodies. and you hear sounds such as gun shots, foot steps, growls etc. And the more and more you kill the more creepy the game gets so that it always keeps you on edge. This will make it so that people will be more reluctant to be a bandit because of all those disadvantages. I saw how the dawing of the Bandit is all scribbled on so that shows that the bandit is clearly losing sanity.
